Embodiment Construction

[0017] The following examples refer to Figure 1-7 .

[0018] The size-adjustable platform of the powder bed 3D printing equipment of the present invention includes a power system 1, a printing workbench 2, a circular sleeve or a square sleeve 3, a fixed circular inner cavity workbench or a fixed square inner cavity workbench 4, a convex Table structure 5, movable circular worktable or movable square worktable 6, connecting hole 7 and printing equipment outer cylinder 8.

[0019] A fixed circular inner cavity workbench or a fixed square inner cavity workbench 4 is divided into two parts: a table top and a connecting track. During the working process, the movable circular workbench or the movable square workbench 6 is driven by the power system 1 to move up and down in the connecting track.

[0020] The movable circular workbench or the movable square workbench 6 is mainly composed of three parts, the uppermost part is the working part of the tabletop, the lower part is conne...

Abstract

The invention discloses a powder bed 3D printing equipment size adjustable and controllable platform for solving the technical problem about the poor compatibility of an existing powder bed 3D printing platform. According to the technical scheme, a power system, a printing workbench, a circular sleeve or square sleeve, a fixed circular inner cavity workbench or fixed square inner cavity workbench,a boss structure, a movable circular workbench or movable square workbench and a printing equipment outer cylinder are included. The printing workbench is connected with the bottom of the movable circular or movable square workbench through a connection hole. The boss structure is designed in the printing equipment outer cylinder. The fixed circular inner cavity workbench or fixed square inner cavity workbench is arranged on the boss structure, and the movable circular workbench or movable square workbench is connected with the printing workbench. Due to existence of the fixed workbench, themovable workbench and the sleeve, the proper printing platform can be selected according to the specific printing piece size and number, the printing efficiency is improved, printing materials are saved, and the printing cost is reduced.

Description

technical field [0001] The invention relates to a powder bed 3D printing platform, in particular to a powder bed 3D printing equipment size adjustable platform. Background technique [0002] 3D printing technology is a rapid prototyping device using light curing, laser sintering and other technologies. The printing equipment is filled with "printing materials" such as liquid or powder, and the "printing materials" are superimposed layer by layer through computer control. 3D printing does not require fixtures, and can process parts of any complex shape. The design of parts is no longer limited by processing methods and clamping. Therefore, 3D printing is widely used in automobiles, aviation, aerospace, biomedicine, energy and power and other fields. [0003] The document "Wen Shifeng, Ji Xiantai. Research status and application progress of laser selective sintering technology [J]. Suzhou Vocational University Journal, 2018." describes in detail the principle and characteris...
